1072166 - [LockScreen] Mapping state changing to signal edge style events

Status: RESOLVED DUPLICATE of bug 1101418

(Firefox OS Graveyard :: Gaia::System::Lockscreen, defect)

Description

[Greg Weng [:snowmantw][:gweng][:λ]]

Current there are two kinds of input of the state machine:

1. Event
2. State

For instance, the 'homepress' is event, and 'passcode on' and 'passcode off' is state . Current implementation would bind these two kinds of input as the transferring input. But as Tim and I discussed, if we split more states, and map the inner state changing to some specific State, we can eliminate the requirements of keeping these inner states:

Old:

---- slide to end --- depends on passcode on off ( SlideUnlock | ShowPasspad )

New:

---- passcode on -> PasscodeOn ---- slide to end ---- SlideToPasscode
----------------------------------- slide to end ---- SlideToUnlock

In the above diagram, we split the original state into two, while the first one can avoid to do the decision relying on the inner state. This is better, but require us to make some changes.

Bug 1101418 would provide what we want.
